Description

The Kubernetes working group is discussing an eviction request API with a cap freeze approaching 0:05. The API introduces eviction interceptors that allow components to hook into pod termination lifecycle events 1:45 and includes a new "target" field that could potentially be extended beyond pods to other resources 3:56.

Key Takeaways:
• The API introduces "soft" eviction type as default, allowing interceptors unlimited time to handle termination gracefully 9:14
• There's debate about making the API pod-specific versus generic to support future extensions like PVCs 5:00
• Naming conventions use pod UID to avoid conflicts when pods are recreated with same name but different UID 26:42
• The API limits interceptors to 30 per domain and 70 total to prevent excessive pod object size 33:53

The team faces pressure to finalize the API before the cap freeze while addressing design questions about extensibility and implementation details 0:24.

So there is not much time uh to actually uh push this forward. Uh so we have like some a couple of conversation points and like I I think like basically the like the main uh like issue is like this is like a very big new API and uh it comes with a lot of scrutiny and like to see like if we are doing things right. So yeah, so we have like some discussions in the cap. I will quickly go through the API and then uh uh we can talk uh about some of the points uh that might uh like need some um like bet…
